I'm stumped for what to get four managers and three supervisors who report to me. Last year I gave them nice picture frames, which seemed to go over well. Three of the managers are women, one is a man. Two of the supervisors are men, one is a woman. I want to get basically the same gift for all of the managers, and the same gift (slightly less $$) for the supervisors. I'm looking to spend $40-50 for the Managers and $30-40 for the supervisors. Any thoughts?
